$PEOIFICATION forming part of Letters Patent No. 416,508, dated December 3, 1889. Application filed December 14, 1888. Serial No. 293,595. (No model.)

To all whom it may concern.-

Beit known that LELWYN DAVID SHEETS,

a resident of Cedar Rapids, in the county of Linn and State of Iowa, a citizen of the United States, have invented a certain new and Improved Vapor-B urner; and I do'hereby declare the following to be a full, clear, and complete description thereof.

My invention consists of a novel construc entof all the others, and so that in case one of the channels, tubes, or conduits becomes clogged from any cause it will not interfere with the operation of the other burners; also to provide the generating-burner with a subflame attachment, so that vapor can be generated at the generating-burner and supplied to any of the other burners without having to bring the generating-burner into use. Furt-hermore, from the center burner there is fed directly downward a flame, the heat of which is concentrated upon the generators by means of a shield, which is arranged to be adjustably attached to the air-tube or stand-pipe of the burner.

That the invention may be fully understood, reference will be had to the annexed specification and accompanying drawings, in wh'ich- Figure 1 is a side view of a vapor-burner as above referred to. Fig. 2 is a plan view of the heating-plate thereof. Fig. 3 is a face or front side view of the burner. Fig. 4 is an inverted plan view of Fig. 3; and Fig. 5 is a vertical section of said burner on line x 00, having the rear part removed. Fig. 6 illustrates the opposite side of Fig. 1 and a central section through the heating-plate and cap of the central burner. Fig. 7 is a detail view taken through the pipe F.

Like letters of reference refer to like parts in the drawings and specification.

The construction, as represented in the drawings, consists of a center burner and the needle-valves for three supplementary and independent burners.

The arrows in Figs. 3, 4, and 5 indicate the direction in which the air-tubes are to be extended to the supplementary burners.

The arrows at a relate to the side burners and the arrows b to a lower burner, which is used in connection with an oven, either outside or inside of the stove-frame, but below the plate thereof. (Said air-tubes are not shown in the drawings.)

Substantially the center burner consists of the heating-plate A, the burner-cap B, vaportube D, generating channel or tube E, and angular pipe F, with needle-valve G, and

drip-cup H.

The heating-plate A is provided with a capsular extension or nipple c, to which is attached the stand-pipe I, as seen in Figs. 1 and 6. The independent generating channel or tube E (also J and K, which will hereinafter be referred to) is in open connection with said nipple c, as seen in Figs. 4 and 6, and it is thus that the gasoline is distributed to the various vapor-generators.

Into the terminal E of the channel E is screwed the pipe F, which leads the vapor to the needle-valve G from said generating-port E,-formed at the under side of the plate A.

The independent generating tubes or channels J and K, above referred to, form an integral part of the under side of the plate A radiating from the nipple c and terminating at J K in a central line opposite through said plate. I

In the terminals J K the pipes L and M are screwed, by means of which vapor is conveyed to the needle-valves N O for the side burners and to the needle valve P for the lower burner, Figs. 3 and 5. Vapor can thus be conveyed to any one of the burners separately, and the independent generators of vapor are provided with a sub-flame or heating-mechanism attachment for this purpose, which is arranged in connection with the pipe F of the center burner, and consists of the branch pipe Q, forming at one side the ICO sleeve for the needle-valve Rand at the other a cylinder S, extending in close proximity to the under side of the heating-plate A, Figs. 3 and 5. Near the lower end of said cylinder 5 S are perforations (Z, to admit of the commingling of air with the vapor discharged through the orifice e of the needle-valve R, as seen in Figs. 3 and 5. The upper end of said cylinder S is flaring and perforated in the face-plate thereof, as seen at f in Fig. 5.

At the junction or union of the pipes F and Q is the seat of the plug-valveT being the stem and F the sleeve of said valve which is kept shut if the center burner is r 5 not to be used. The vapor in that instance is only used for sustaining the sub-flame underneath the heating-plate, which, owing to its location, is more effective in the generation of vapor within the independent tubes or channels E, J, and K than the center burner would be if kept in operation. The heatlug-plate A is of a dish shape and has a lug g extending from the rear side thereof, by means of which it can be attached to the stove-frame. Through the central hubV the tube D protrudes into the combustion-chamher or interior of the cap B, as seen in Fig. (3. Said cap is set into an annular recess 72, Fig. 5, of the plate A. A part of the vapor which is conveyed through the vapor-tube D into the said combustion-chamber passes through the perforations i in the bottom of the plate A, ignites and assists in the generation of vapor in the independent tubes or channels E, J, and K, and atthe upper part of the stand-pipe I, Figs. 2 and (i. The shield V, which, by means of a set-screw a is adj ustable, and preferably attached to the tube D, Figs. 3, at, and 6, concentrates upon the generaters the heat eleminated by the flame through the openings 1', thereby rendering the heat certain and effective for the purpose designed.

In describing the primary operation of said burner it is supposed that all the valves are closed, while to start the ignition thereof the plug-valve T and needle-valve G are opened, which admits of a discharge of gasoline from the needle-valve G. This dis- 5o charge will pass up through the tube D, colleet on the bottom of the heating-plate A, and find its course through the opening 7.; down into the drip-cup H. \Vhen said cup is nearly filled, the valve T is shut and the gasoline ignited for the initial heat in the generation of' vapor. \Vhen vapor is once generatethone or more of the said generators maybe put in operation independently of the others, and if the center burner, which ordinarily generates vapor for all the burners, is not to be used, then the sub-flame or heating attachment is to be set in operation for generating vapor for the burners to be used. The sub-flame may be reduced to a small burning jet by means of the regulating-valve connected with the sub-flame mechanism. After all the burners are shut off the operator can relight one or more of the burners at intervals by this means; hence the stove is constantly kept in ready condition for use at a minuniuin consumption of liquid fuel. The needle-valve Gof the center burner, when once set, does not need to be closed every time the center burner is to be stopped, the plug-valve T being used for that purpose. Should, however, the orifice of said valve become clogged up, then only the said valve need to be shut in order to pierce the needle through the orifice thereof for clearance.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the stand-pipe, the heating-plate A, provided with a series of holes 1', the vapor-tube D, the shield V, and set-screw (1, whereby the shield is made vertically adjustable, substantially as shown.

2. The combination of the stand-pipe, the heating plate A, secured thereto and provided with a series of channels which connect directly with the stand-pipe, and provided with a series of holes 1', and the vaporpipe D, with the vertically'adjnstable shield V, substantially as described.

8. The combination of the stand-pipe, the burner connected thereto, the pipe S, extending from the stand-pipe, and the valve R, placed therein, the pipe being provided with the air-hole (Z beyond the end of the valve, and the perforations f through its upperend, whereby the generator-burner can be kept hot when not in actual use, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
